When emails addresses are private, squash merges always use
`@noreply.localhost` for the author of the squash commit. And the author
is redundantly added as a co-author in the commit message.
Also without private mails, the redundant co-author is possible when
committing with a signature that's different than the user full name and
primary email.
Now try to find a commit by the same user in the list of commits, and
prefer the signature from that over one constructed from the account
settings.

* Remove unnecessary ToTrustedCmdArgs calls
* the FAQ in #22678
* Quote: When using ToTrustedCmdArgs, the code will be very complex (see
the changes for examples). Then developers and reviewers can know that
something might be unreasonable.
* The `signArg` couldn't be empty, it's either `-S{keyID}` or
`--no-gpg-sign`.
* Use `signKeyID` instead, add comment "empty for no-sign, non-empty to
sign"
* 5-line code could be extracted to a common `NewGitCommandCommit()` to
handle the `signKeyID`, but I think it's not a must, current code is
clear enough.
The merge and update branch code was previously a little tangled and had
some very long functions. The functions were not very clear in their
reasoning and there were deficiencies in their logging and at least one
bug in the handling of LFS for update by rebase.
This PR substantially refactors this code and splits things out to into
separate functions. It also attempts to tidy up the calls by wrapping
things in "context"s. There are also attempts to improve logging when
there are errors.
